PNEUMATIG TIRE.

To all whom 'it may concern:

Be it known that, l, ALSIME BERNIER, a citizen of the United States, residing at Providence, in the State of Rhode Island, have invented a new and useful lmprovement in Pneumatic rlires, of Which the following is a specification.

The nature of my 'invention consists in the improved combination of crescent sha ed inflated elements and an annular hol ing member, with the inflated tube and the outer covering of a pneumatic tire as hereinafter set forth.

In the accompanying drawings z--Figure l represents apartial longitudinal section of a pneumatic tire embodying my improvement. Fig. 2 represents an enlarged transverse section takenin the line 2, 2, of Fig. l. Fig. 3 represents an enlarged perspective View oi'v one of the inflated elements. Fig. d represents a perspective View showing the construction of the annular number for. holding the crescent shaped inflated elements. Fig. 5 represents a sectional v'iew showing a modification.

ln the drawing, A represents the rim of the Wheel, and B is the annular inflatable rubber tube. 'lhev crescent shaped elements at the inner side of the annular exible holding member D, the said holding member being provided with the inwardly turned edges b, as shown in Fig. fl, which serve to retain the elements C, C, in the said pochets. rlhe indated elements C, C, are provided vvith the external shoulders c, c, which are arranged to bear `upon the edges of the partitions d cl, between the pockets E, E, of tbe annular holding member D, and by this means the said elements will be properly supported lwhen the tire is being used under pecication of Letters Patent.

the indatable rubber tube B, are inclosed for attachment to the Wheel A, qWitlnn the attaching tread lt..

ln the modiioation shown in Fig. 5, a projecting flap e is employed which lapsy onto the. succeeding element, vvhereb the joint f between the said elements vvill be covered. e

'l claim as my invention:

1. In a pneumatic tire, the combination of an annular flexible holding member, provided at its inner side with a series of receivin pockets with intervening artitions and Wlth inwardly turned edges, 1n ated elements made crescent shaped in cross-section and held in the pockets oi the said holding member and having external shoulders which bear upon the ed 'es of the partitions between the said poc ets, whereby the said elements will `be supported when the tire is being used under pressure, an inflated rubber tube pressing upon the said indated elements, and the tire tread which serves for attachment to the rim of the Wheel.

2. lin a pneumatic tire, the combination o an annuiar holding member provided with a series oi2 receiving pockets at its inner side With intervening partitions, inflated elements made crescent shaped in cross-section and having external shoulders which bear u'pon the edges olf the partitions between the said pockets, and also have a projecting flap for lapping Contact with the inner side of the adjoining inflated element, with an inflated .rubber tube, and the tire tread 4which serves for attachment to the rim of the wheel.
